BSW21 PNP Transistor

The BSW21 is a bipolar junction transistor (BJT) with an PNP-type configuration. That means the BSW21 transistor has a negatively charged layer between two positively charged layers. This transistor has three terminals Base, Collector, and Emitter.

The BSW21 transistor symbol shows an arrow from the emitter into the base. This means that the current flows from emitter to collector terminal.

Circuit diagram symbol of the BSW21 transistor as follows.
